Need advice on how to sound insulate my room


Need advice on how to insulate my stereo room. My rig is is in the finished basement of my home. Problem is that the house is old'ish and the sound reverberates throughout the house - probably through the basement drywall and ceiling.

The upstairs floors are hardwood, with throw rugs. The walls are plaster on lathe.

The basement ceiling is drywall. However, the ceiling height is only about 8 feet, so a drop ceiling is not an option.

Not sure there's much I can do, but any suggestions have to be aesthetically nice or my wife will object.

Thanks

There is a new drywall product called quietrock that is very effective for reducing noise and if funds permit you could drill and blow cellulose insulation in your basement ceiling. Both are excellent products for reducing sound. Good Luck.
Liz, the answer to your questions is yes and yes. Check my system gear.

Was wondering if there is such a thing as sound absorption tile panels that I could glue to the ceiling. Maybe cork board for the walls would help.

Shame is, the room and my system seem to work well together -- makes for a good sound presenation. Killing the resonance might kill the sound.
Lead wall paper. Yes, there is such a thing, but expensive. Often used as an underlay in floors. I used it in a media room that I built some time ago. It needs to be sealed as it could be an environmental hazard. If you have children, forget about it.
